SPECIFICATION forming part of Letters Patent No. 708,606, datedSeptember 9, 1902.

Application filed April 18, 1902.

Serial No. 103,578. (No model.)

To all whom t may concern:

Be it known that I, EDWARD F. WIXTED, a citizen of the United States,residing in the city of Chicago, county of Cook, and State of Illinois,have invented a new and useful lmprovement in Ventilating-Ts, of whichthe following is a specification.

My invention relates to ventilating-Ts for use in sanitary plumbing.

It is well known to those skilled in the art of plumbing that inusingthe ordinary waterseal traps it is necessary to provide means forpreventing siphonage,and one of themethods employed for this purpose isby the use of a Ventilating-T located between the trap and the stack ormain vertical soil-pipe. The partitions wherein such stacks are locatedare frequently so thin as to greatly restrict the direction in which thehorizontal opening of the T may extend. This restriction is due to thebulky form of the ordinary Ventilating-T at the juncture of the vent andT. f

The object of my invention is to provide a Ventilating-T of suchconstruction that a wide range of adjustment is permitted for thehorizontal pipe, even when the stack is located in a partition hardlygreater than the exterior diameter of said stack. I attain this objectby the mechanism illustrated in the accompanying drawings, in which-Figure 1 is a side View of the T. Fig. 2 is a plan sectional view of theT, taken on the line 2 2, Fig. 1. There is also indicated in dottedlines the possible adjustment of the T when located in a thin partition.Fig. 3 is a View in elevation indicating the manner of locating the T inthe partition and floor of al building.

Similarletters refer to similarparts through out the several Views.

a represents a portion of the stack or soilpipe located above the T, thejoint b of the T being adapted to receive its lower extremity.

c is the lower extremity of the T and is received by the lower portion dof the stack.

The horizontal branch e is adapted to join with the pipe f. i The vent gcommences at a point near the top of said horizontal branch and is solocated that no part of the juncture is Within the line of the verticalstack. From its junction with the branch e the vent extends upwardly andalso curves laterally in such a manner as to come at the side of thevertical portion of the T. The upper extremity or mouth of the ventg islocated at the side of the vertical portion of the T, so that no part ofsaid mouth is directly over any portion of said horizontal branch e.Moreover, said mouth is so located relatively to said vertical portionof the T as to lie sub- 6o stantially adjacent to a reference-planeextending transverse to the horizontal branch'e andv tangent to theVertical portion of said T at its juncture with said horizontal branch.

The advantages of this construction will be evident by referring toFigs. 2 and 3 of the drawings, in which h h represent the walls of apartition, fi represents the floor, j the ceilingbelow, and k k thejoists of a building.A The walls of the partition are shown to be at 7oa distance apart slightly greater than the diameter of the stack. Thepoint of juncture of the vent and the branch e lies between the lioor't' and ceilingj, and the T may therefore be rotated without interferingwith the floor or ceiling. The mouth of the vent, however, comes upbetween the walls h h of the partition, and when said T is squared thesaid mouth is adjacent to the front wall of the partition. If desired,the T may be swung 8o "in the direction of the curved arrow, Fig. 2,

until the vent comes into contact with the rear one of the walls h, asshown in dotted lines. This permits a wide range of adjustment in onedirection, and by making right7 85 and left7 Ts there is practically norestriction as to direction of the horizontal branch e. All lateralbends are avoided, thereby giving a straight run from the trap or closetto the main stack. 9o

Another advantageous feature of this T is that the vent lies nearer tothe mouth of the horizontal branch, so that when connected up thejuncture of said vent and branche may closely approach the trap, therebyrendering it easily possible to conformto the usual statutoryrequirements for plumbing.

What I claim as new, and desire to secure by Letters Patent, is

1. A Ventilating-T having a horizontal and roo a vertical branch, and avent open at the top and joining with the said horizontal branch out ofline with said vertical branch.

` 2. In a Ventilating-T, the combination of a branch, a vertical branch,and a vent, the juncture of the vent With said horizontal branch lyingWh olly on said horizontal branch and the mouth of said vent lyingsubstantially adjacent to said vertical branch; and the mouth of saidvent lying between reference-planes extending transversely to saidhorizontal branch and tangent to said Vertical branch.
